I am trying to create a reference point. First, I created two axes as reference geometry. Then I use Insert -> Reference Geometry -> Point -> Intersection and then I select the two axes that I have created. The names of these two axes appear then in the "Reference entities" box. But then, when I press on the green tick mark, these name disappear from there, so the "Reference entities" box becomes empty. And thus I cannot complete the process of creating a reference point. I've tried that many times, always the same.
Why does it happen so?
